API 6AV1 Rated Boarding Shutdown Valve

API-6AV1RatedBoardingShutdownValveThe CORTEC Model “D” Series Ball Valve is a double trunnion design. The ball is held firmly in place by two large trunnion blocks, allowing only rotational movement. With the ball always perfectly aligned, independent spring-loaded upstream and downstream seats are always in contact with the ball, which provides an effective tight seal even at very low pressures. The Double Trunnion design permits ease of operation and significantly reduces torque. Our use of robust double trunnions and spring-loaded seats affords the most reliable configuration. The “D” Series Ball Valve can be supplied with polymeric or metal seats. Every valve is DBB (Double Block & Bleed) and is equipped with stainless steel vent fitting that allows the body cavity to be easily bled.
